Answers Latest Update 2023 (Verified Answers)
Neonatal Period - Correct Answers ✅-Defined as the first 28 days after birth
-Newborn adapts to a brighter & cooler environment
-Physiologic & behavioral changes occur quickly
-The nurse & parents must be aware of any deviations from the norm for
early identification & prompt interventions
Assessment Findings - Correct Answers ✅-Transition
-6-10 hours
-Physiological changes
-Periods of reactivity
-Physical assessments
-Reflexes
Umbilical cord - Correct Answers ✅Vein carries oxygenated blood from
placenta to uterus
Ductus Venosus - Correct Answers ✅permits most of umbilical vein blood to
bypass liver & merge with blood in vena cava
-Reaches heart sooner

Answers Latest Update 2023 (Verified Answers)
Foramen ovale - Correct Answers ✅allows blood entering right atrium to
cross to left atrium
Ductus Arteriosus - Correct Answers ✅connects the pulmonary artery to the
aorta, allowing for bypass of the pulmonary circuit
Placenta - Correct Answers ✅supplies oxygen, nutrients & removes waste
products
Cardiovascular Adaptations - Correct Answers ✅
At birth - Correct Answers ✅-Fetal circulation must convert to newborn
-Placental pulmonary exchange
-Release of epinephrine & norepinephrine
-Stimulate increased cardiac output
Cont.. - Correct Answers ✅-Umbilical cord is clamped
-First breath taken & lungs begin to function
,NEONATAL NURSING Study Guide Questions and
Answers Latest Update 2023 (Verified Answers)
-Pressure changes occur
-Left atrium> right atrium
-Foramen ovale closes
-Oxygenated & non-oxygenated blood no longer mixes
Cont.. - Correct Answers ✅-Ductus Arteriosus becomes functionally closed
within the first few hours after birth
-Closure is signaled by high oxygen content of aortic blood
-Results from gas exchange in the lungs
-Pulmonary vascular resistance decreases
-Pulmonary blood flow increases & oxygen exchange occurs in the lungs
Cont.. - Correct Answers ✅-Ductus Venosus closes within a few days after
birth
-Due to activation of functional liver
-Liver takes over functions of placenta
-Two umbilical arteries & one vein constrict at birth & become ligaments

Additional CV Changes - Correct Answers ✅
After birth - Correct Answers ✅-Heart Rate- 120-180bpm
-Will decrease to 120-130bpm
-Crying, movement & wakefulness will cause an increase in HR & blood
pressure
Cont.. - Correct Answers ✅-Difficulty compensating
-Tachycardia may reflect:
-Dehydration, CV disease, drug withdrawal
-Bradycardia may reflect:
-Apnea, hypoxia
-Delayed cord clamping may improve newborn's CV/pulmonary adaptation
Respiratory Adaptations - Correct Answers ✅-Hypercapnia, hypoxia &
acidosis from normal labor trigger 1st breath & subsequent respirations
-Also environmental factors e.g. noise & light
-Surfactant provides the lungs with stability for gas exchange
